while friction between the strip members as one slides upon theother will be small.

' Another feature of the present invention is that the seal effected by the weather strip mem-bers' is located neXt to the parting strip of the window frame, whereby the entrance of air is effectively prevented and liability of the side members of the sashes warping and binding is reduced to a minimum.

Still another feature is the provision of a simple, durable and efficient weather strip construction embodying means to properly guide the sashes to further guard against binding thereof, and means to permit limited f yielding ofthe sash-es in directions parallel and transverse to the plane of the same, so that smooth, easy movement of the sashes in the frame is insuredlunder various conditions of use.

The invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing, and claimed.

In the drawing Figure 1 is a cross-section of one side of a window frame and the two sliding sashes therein, provided with weatherV strips embodying the present invention; and

FiguresQ and 3 are fragmentary perspec- 140 tive views, showing the sash and frame4 weather strip members, respectively, of the weather strips shown in Figure l.

Referring in detail to the drawing, 5 indicates a window frame for sliding sashes, and

` i5 6 and 7 are stops for the sashes carried by the frame 5. A parting strip 8 is secured to the frame, as shown. The two sashes 9 and l0 are adapted to slide in the frame, each having its side members received and guided in the channel formed between the parting strip tight seal is had between the strip members,

This insures an efficient seal against the entrance of air and at the same time the wall 23 may give or yield to avoidl binding and minimize friction. .Holes 24 may be provided in the body 18 to facilitate attachment of this strip member to the sash,

to be attached to the outer edge of the side sash member and provided at one side with a right angle extension formed with three folds to provide a double-wall groove member adapted to receivesa-id hook portion, the outer two walls of said groove member being spaced to provide a free yieldable outermost wall adapted to contact the inner face of the right angle extension of the first strip member. i j: In testimony whereof I aHiX my signature.

From the above description, itwill be apparent that .the weather stripv will be very durable, will effectively operate `to the end delsired in the use thereof, andmay be readily applied. ,d v
